LazyValidatorForm not accepting multiple selects

LazyValidatorForm not accepting multiple selects

2007-11-04       - By Donald Rosengartner

 Back

I recently joined a team using struts 1.3.8 and LazyValidatorForm. I can not
seem to get the following html:select to work. I have tried modifying the
datatype of the form bean property(ArrayList, String[], etc). String[] made the
first of my selections' values available in the Action, but no other selections
posted. I have javascript in place to make these selected options "selected",
so I'm sure the post is not the issue. Switching to the classic ActionForm, all
values become available with no JSP/javascript changes. My code follows:
<bean:define id="teams" name="DMAForm" property="teamCollection" type="java
.util.List"></bean:define>
<html:select property="schdTrnmtGamesSelected" multiple="true" size="10"
styleId="selectedTeams">
<html:options collection="teams" property="teamId" labelProperty="teamName" />
</html:select> Classic Struts accessor - String[] selectedTeams = dmaForm
.getSchdTrnmtGamesSelected();with LazyValidatorForm -String[] selectedTeams =
(String[]) dmaUserForm.get("schdTrnmtGamesSelected");// this gives
ClassCastException, but the next is fine at runtimeString selectedTeams =
(String) dmaUserForm.get("schdTrnmtGamesSelected");// defeats the purpose, as I
need all selections that I intended to post
I also tried to access as indexed property of the map, such as String
selectedTeam1 = (String) dmaUserForm.get("schdTrnmtGamesSelected", 0);String
selectedTeam2 = (String) dmaUserForm.get("schdTrnmtGamesSelected", 1);The
zeroeth index returns the same value as that above without the index[0], but
subsequent values of the index are not populated in the form.
Searching the archives for information on this, I find that String[] is the
correct datatype, but little if any information about mutiple=true concurrently
used with LazyValidatorForm.I need to get this working as I have a tiles header
that requires a lazyValidatorForm in scope. I have a workaround which forwards
to the init method(as if to read the calling page for the first time), however
I have other pages that are top-level and are broken until I find a fix.Thanks
in advance for suggestions givenD. Duane RosengartnerSogeti - Dallas Unit
